Examples disclosed herein relate to provisioning a network device in a stack. In an example, a master network device in a stack may detect a new network device in the stack. In response to detecting, master network device may determine whether a member network device of the stack is missing. In response to determining that the member network device of the stack is missing, master network device may identify each active adjacent member of the member network device. The master network device may determine whether each active adjacent member of the member network device has detected the new network device in the stack. In response to determining that each active adjacent member of the member network device has detected the new network device in the stack, master network device may provision the new network device with a member ID of the member network device to the stack.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method comprising: detecting, by a master network device in a stack, a new network device in the stack; in response to detecting, determining, by the master network device, whether a member network device of the stack is missing; in response to determining that the member network device of the stack is missing, identifying, by the master network device, each active adjacent member of the member network device; determining, by the master network device, whether each active adjacent member of the member network device has detected the new network device in the stack; and in response to determining that each active adjacent member of the member network device has detected the new network device in the stack, provisioning, by the master network device, the new network device with a member ID of the member network device to the stack.
2. The method of claim 1 , further comprising: applying, by the master network device, a configuration setting of the member network device to the new network device.
3. The method of claim 1 , wherein determining whether each active adjacent member of the member network device has detected the new network device in the stack comprises: determining that each active adjacent member of the member network device has detected the new network device on a respective port where the member network device was previously connected.
4. The method of claim 1 , wherein identifying comprises: identifying, by the master network device, each active adjacent member of the member network device from a database present on the master network device.
5. The method of claim 1 , wherein detecting comprises: receiving, by the master network device, information related to the new network device from the new network device; detecting, by the master network device, whether the information preexists on the master network device; and in response to a determination that the information does not preexist on the master network device, identifying, by the master network device, the new network device as a new addition to the stack.
6. The method of claim 1 , wherein the information comprises one of a device type of the new network device and a MAC address of the new network device.
7. The method of claim 1 , wherein member network devices of the stack, including the new network device, are arranged in a Ring topology.
8. A network device comprising: a detection engine to detect a new network device in a stack; a determination engine to, in response to detection, determine whether a member network device of the stack is missing; an identification engine to, in response to the determination that the member network device of the stack is missing, identify each active adjacent member of the member network device; the determination engine to determine whether each active adjacent member of the member network device has detected the new network device in the stack; and a provisioning engine to: in response to the determination that each active adjacent member of the member network device has detected the new network device in the stack, provision the new network device with a member ID of the member network device to the stack; and apply a configuration setting of the member network device to the new network device.
9. The network device of claim 8 , wherein the network device manages a control plane of the stack.
10. The network device of claim 8 , wherein the member ID includes a stack member number.
11. The network device of claim 8 , wherein the provisioning engine is to unprovision the member network device from the stack.
12. The network device of claim 8 , wherein the provisioning engine is to: in response to a determination that the member network device of the stack is not missing, provision the new network device with a new member ID to the stack.
13. The network device of claim 8 , wherein member network devices of the stack, including the new network device, are arranged in a chain topology.
14. A non-transitory machine-readable storage medium comprising instructions, the instructions executable by a processor to: detect, by a master network switch in a stack, a new network switch in the stack; in response to detection, determine, by the master network switch, whether a member network switch of the stack is missing; in response to a determination that the member network switch of the stack is missing, identify, by the master network switch, each active adjacent member of the member network switch; determine, by the master network switch, whether each active adjacent member of the member network switch has detected the new network switch in the stack; and in response to a determination that each active adjacent member of the member network switch has detected the new network switch in the stack, provision, by the master network switch, the new network switch with a member ID of the member network switch to the stack.
15. The storage medium of claim 14 , wherein the instructions to determine whether the member network switch of the stack is missing comprises instructions to: send, by the master network switch, a heartbeat message to the member network switch; and determine, by the master network switch, that no response is received to the heartbeat message from the member network switch.
16. The storage medium of claim 14 , further comprising instructions to unprovision, by the member network switch, the member network switch from the stack.
17. The storage medium of claim 14 , further comprising instructions to provision, by the master network switch, the new network switch with a new member ID to the stack, in response to a determination that the member network switch of the stack is not missing.
18. The storage medium of claim 14 , wherein the instructions to determine whether each active adjacent member of the member network switch has detected the new network switch in the stack comprises instructions to: receive, by the master network switch, information related to each active adjacent member of the new network switch from the new network switch; and determine, based on the information, that each active adjacent member of the new network switch has detected the new network switch on a respective port where the member network switch was previously connected.
19. The storage medium of claim 18 , wherein the information related to each active adjacent member of the new network switch comprises at least one of a device type of an active adjacent member of the new network switch, a MAC address of the active adjacent member, and a port identifier of a port on the active adjacent member where the new network switch is connected.
20. The storage medium of claim 14 , wherein member network switches of the stack, including the new network switch, are arranged in a mesh topology.
